Sometimes you print out an object, and it just prints the class name and reference ID, like this:


Illustration of a frowning stick figure with curly hair.

person (thinking): “ugh, thanks, very helpful… “

Implementing a custom string representation for a class you’re often printing out can save a LOT of time. The name of the method you need to implement is: - Python: .__str__ - Ruby: .to_s - JavaScript: .toString - Java: .toString - Go: String()

Also, pretty-printing libraries (like pprint in Python or awesome_print in Ruby) are great for printing out arrays/hashmaps.
